A stirring and romantic fantasy novel from the Newbery Honor author of Ella Enchanted, a noble girl learns that her parents were of the despised underclass, and she must raise a rebellion on behalf of her people.

Peregrine strives to live up to the ideal of her people, the Latki-and to impress her parents: affectionate Lord Tove, who despises only the Bamarre, and stern Lady Klausine. Perry runs the fastest, speaks her mind, and doesn’t give much thought to the castle’s Bamarre servants, whom she knows to be weak and cowardly.

But just as she’s about to join her father on the front lines, she is visited by the fairy Halina, who reveals that Perry isn’t Latki-born. She is Bamarre. The fairy issues a daunting challenge: against the Lakti power, Perry must free her people from tyranny.
